Just tell that to your child that has to submit a assignment before
midnight or get zero on 20% of the year's marks.  There are plenty
of cases where uploads are time critical there are also time where
it really doesn't matter.

Once you get over a certain threshold more download speed doesn't
buy as much as more upload speed.  For movies you want the data
there before you need to display it.  It really doesn't matter if
it is 30 seconds before or 20 minutes before, you only consume the
data so fast.

If the network supported it this would be typical of a household
with teenagers.  People adapt their usage to the constraints
presented.  That doesn't mean they are necessarially happy with the
constraints.  Don't take lack of complaints as indicating people
don't want things improved.

As speed increases the importance of more speed decreases.  We get
to the point where thing happen fast enough.  We also start to be
limited by things other than link speed.
